COUNTER PENCIL.

Application filed March 17, 1923. Serial No. 625,849.

My invention is a counter-pencil and it consists in the combinations, constructions and arrangements. herein described and claimed.

An object of the invention is to prov de a pencil afiording facilities for indicat ng the number of check marks made therewlth at an particular time.

A urther object of the invention is to provide a pencil of the character described having a rotatable scaling element adapted to be moved along a line on a drawing or other schedule and to actuate means provided in the pencil for indicating the total length of the respective lines traversed by the rotatable element.

A further object of the invention is to provide a pencil of the character described which embodies a novel means for releasably and adjustably holding a length of lead.

Other objects and advantages will be apparent from the following description, considered in conjunction with the accompanying drawings, forming a part of this app cation, in which Figure 1 is a longitudinal central sectional view through a pencil embodying my invention,

Figure 2 is a longitudinal section through the pencil, the view being taken substantially along the line 2-2 of Figure 1,

Figure 3 is a longitudinal section through the pencil, the view being taken substantially along the line 33 of Figure 1,

Figure 4 is a relatively reduced side elevation of the pencil,

Figure 5 is a transverse section along the line 55 of Figure 1, and

t Figure 6 is a transverse section along the line 6-6 of Figure 1.

Referring now to the drawings, the numeral 1 designates a tubular pencil casing or barrel and 2 is a core interfitting a portion of the barrel 1, being of less length than the latterand extending from the rear end thereof in the barrel 1 and terminating at an appreciable distance from the forward end of the barrel. The core 2 is recessed at its rearward end as indicated at 3 to accommodate 'lng portion 14 atits free an endless member or indicator tape 4 which preferably is made of a light gauge flexible metallic material and is trained about pulleys 5, 6, 7 and 8 respectively. Each of the pulleys 5, 6, 7 and 8 preferably comprises a peripheral portion made of rubber or like material disposed upon a metallic bushing rotatably supported "upon stub shafts or journal'pins supported in the Walls of the recess 3. In the embodiment of the invention illustrated, the stub shafts or journal pins for the respective pulleys are indicated at 5 6, 7 and 8 respectively.

The pulley 8 is larger diametrically than the remaining pulleys and the pulleys 6 and 7 are spaced transversely of the core so that the pulley 5 may be disposed with the axis thereof located in the longitudinal plane passing equi-distant between the axes of the pulleys 6 and 7 and through the axis of the pulley 8. With this arrangement, an endless indicator or number tape of relatively great length may be accommodatedand supported on rotatable pulleys in a recess of a given size and each portion of the outer face of the number or indicator tape will be presented to view in its turn through an inspection opening 9 opening through the core in line with an opening 10 in the barrel. The number or indicator tape 4: is provided on its outer face with a series of numerals arranged in 80 two rows extending side by side longitudinally of the tape. The numerals of the two rows on the tape4respectivelyindicatetens and units so that the numerals 00 to 99 are provided in consecutive order on the tape 4.

The means whereby movement may be imparted to the tape 4 will now be described. Such means include a slidableithimble 11 interfitting the barrel at the forward end of the latter and extending tov adjacent relation to the forward end of the core. A pusher arm 12 pivotally attached at 13 to the thimble 11 at the rearward end of the latter is provided with a laterally extending engagend and extends in a slot 15 in the core 2 in overlying relation to one lateral marginal portion of the tape 4. Said lateral marginal portion of the tape is notched at regular intervals to provide a series of lugs 16, there being 2. lug 16 for and in transverse alignment with each of the numerals in the units row on the tape 4. A curved spring 17 secured at one end to the pusher arm 12 and reacting adjacent to its other end against the inner wall of the barrel 1 tends to force the free end portion of the pusher arm toward the tape 4 so that the end portion 14 on the pusher arm will front end lar flange 25 extending engage with the lugs 16. It is intended that the engaging portion 14 of the pusher arm 12 shall engage the lugs 16 only when the pusher arm is being moved in a manner to be hereinafter described toward the rear end of the valve'and'that the pusher arm 12 shall disengage the lugs 16 upon return movement of the pusher arm. To this end. the inner wall of the engaging portion 14 may be of each lug 16 facing the rearward end of the barrel may be inclined or beveled so that the beveled wall of the engaging portion 14 will ride thereover out of engagement therewith when the pusher arm 12 is moved bodily toward the forward end of the barrel.

A stop screw in threaded engagement with an axial socket 19 in the forward end of the core is adjusted in respect to the rearward end of the thimble 11 so that the latter is permitted to move rearwardly in the barrel a distance equal to the, space between the centers of each two adjacent lugs 16 and in consequence the number or indicator tape 4 will be moved at each rearward movement of the thimble against the stop screw 18 a distance equal to the distance between each two consecutive numerals of the units row on the tape. An expansion spring 20 surrounding the protruding portion of the stop screw and disposed between the adjacent ends of the core 2 and thimble 11 serves to return the latter to the position illustrated in Figures 1, 2 and 3. A guide pin 21 carried by thebarrel works in a longitudinal slot 22 in the outer wall of the thimble and holds the latter against rotation within the barrel. In this manner, the pusher arm 12 is maintained in a desired position in respect to the lugs 16 at the one edge of the tape 4.

A ring 23 threadedly engaging a reduced portion 24 of the thimble 11 is provided with an inwardl extending annuheyond the inner wall of the thimble 11 into engagement with anoutwardly extending annular flange 26 at the rearward end of a rotatable tubular pencil tip 27. The flange 25 extends inwardly beyond the outer edge of the flange 26 and holds the latter close to the thimble. whereby the tip 27 will be held in axial alignment with the thimble 11, and against any appreciable axial movement relatively to the latter. A ferrule 28 having a bore 29 receiving beveled or inclined and the side wall P at its rearward end accommodating the ring 23 and being threadedly engaged at 31 With the forward end of the barrel 1, whereby the forward movement of the thimble 11 and the parts mentioned -as being connected therewith relatively to the barrel is limited.

As hereinbefore recited, it is desirable that the thimble 11 shall be moved rearwardly in the barrel to actuate the number or indicator tape in the manner described when a pressure slightly nary is applied in making a mark wlth the pencil. To this end, a length of lead or like mark producing substance 32 is extended through the bore of the tip 27 to rest at its rearward end in a socket 33 provided at the center of a lead adjusting disk 34 which is in threaded engagement with internal threads 35 on the thimble. The tip 27 is rovided with a plurality of diskoperating rods 35 extending from the rearward end of the tip in parallel relation to the axis of the latter through openings 37 in the disk 34 The respective openings 37 are located between the axis of the disk and the peripheral wall thereof, whereby rotation of the tip 27 will cause the disk 34 to move in engagement with the threads 35 relatively to the thimble 11, thus moving the lead 32 in the direction of its length and extending it as required to compensate for wear on the point thereof. It will be noted that the arrangement just described for adjust ng the length of lead 32 relatively to the tlp does not in any way interfere with the sliding movement of the thimble 11 in the barrel greater than ordito effect movement of the number or indi- I cator tape 4 in the manner described.

In order to enlarge the range of numbers which may be indicated by a pencil embodying the invention, I rovide a second number tape or band 38 w ich is disposed within a recess 39 in the core 2 alongside of the recess 3 and being in open communication for part of its length with the latter.

Spaced apart rotatable pulleys or rollers 40,

41 respectively are disposed within the recess 39 for supporting the number tape 38,

numerals produced on the band or tape 38. The teeth of the gear 44 are adapted to be engaged by a relatively long lug or tooth projection 45 on the tape or band 4. whereby the tape or band 38 will be moved a distance equal to the spacing between the two adjawith the numerals on one of two juxtaposed rows of caused by operation of the cent numerals in the said one row on the tape 38 when the tape 4 has been moved through a complete cycle. The numerals 0n the tape 38 when considered in association with the numerals on the tape 4 represent hundreds and thousands and are arranged to read consecutively from 00 to 60-. Itof course will be understood that the numerals in the row indicating hundreds are the numerals which are spaced apart distances corresponding to the dis tances between the teeth of the gear 44 and that therefore any number between 00 and 6000 may be indicated when the tapes 4 and 38 are operated in the manner described. A hand wheel 46 on the extending end of the shaft 43 may be turned to effect rotation of the roller 41 and gear 44 in the direction opposite that occasioned by the operation of the tape 4 in the manner described, whereby the tapes 4 and 38 may be returned to initial position after each counting operation.

The numerals on the tape 38 may be observed through an opening 47 provided in {)he C(ile 2 in line with the opening 10 of the arre The barrel 1 is closed at its rearward end by a cap 48 provided with an opening 49 in which extends a friction roller 50-secured to a shaft 51 which is journaled in aligned openings formed in lugs rearwardly from opposite sides of the opening 49. The shaft 51 extends laterally of the cap 48 and a scaling wheel or disk 54 is secured thereon by means of a headed pin 55 in threaded engagement with an axial socket in the outer end of the shaft 51. The arrangement is such that the rotation of the wheel 54 will cause rotation of the shaft 51 and of the friction roller 50. The latter is in frictional contact with the tape 4 and consequently rotation of the wheel 54 causes movement of the tape 4 in a manner similar to that hereinbefore described as being pusher arm 12. The wheel 54 is preferably provided with a rim 56 made of rubber or like material so that its contact with a sheet of paper will not result in injury to the paper. A pointer 57 is supported at one end upon the cap 48, as at 58 and is provided intermediately with an opening through which the headed pin 55 extends whereby the free end portion of the pointer will be held in s aced parallel relation to the outer face of t e wheel 54.

From the foregoing description of the various parts of the device, the o eration thereof may be readily understood. he device is designed primarily although not necessarily for use in checking and counting the number of pieces of lumber of the same size on a schedule or other list. In operating the device, pressure beyond that ordinarily used in pressing the point of the lead against the paper containing the list is 52, 53 extending employed when making a check mark oppos1te each item. As a result, the thimble 11 is moved rearwardl against the stop screw 18 each time a c eck mark is made and the indicator tapes 4 and 38 are operated because of the engagement of the pusher arm 12 with the lugs 16 on the indicator tape 4, as has been hereinbefore described 1n detail. The number of items checked on a plan or other schedule will thus be indicated. Should the work of checking the items be interrupted, the result at the time of the interruption will be indicated when the work is resumed.

The device is also particularly well adapted for use in determining the aggregate length of a plurality of like items represented by lines on a plan or drawing drawn to scale. In determining the aggregate length of such items, the indicator or pointer 57 is placed at one end of each line representing an item and the wheel 54 is moved in rolling contact on the surface of the plan or drawing to the other end of the line representin the item. Motion will be trans mitted to t e tapes 4 and 38 from the wheel 54. to the shaft 51 and friction roller 50.

movement of the wheel 54 along a line onequarter inch in length will cause the tape 4 to be advanced a distance equal to the distance between two adjacent lugs 16 or in other words a distance suflicient to indicate one unit, the value of each unit being one foot when the length of pieces of lumber is being determined.

It of course will be manifest that. wheels 54 of various diametersmay be used interchangeably to adapt the device for use in scaling lines drawn to various scales. With the construction illustrated, the wheel 54 may be removed and the roller 50 used to traverse lines of a 4; scale.

Obviously, my invention is susceptible of embodiment in forms other than that illustrated in the accompanying drawing and I therefore consider as my own all modifications and adaptations of the form of the device herein described which fairly fall within the scope of the appended claims.

I claim 1. A device of the character described comprising a pencil casing having a lateral aperture, an endless indicator tape movably sup. orted within the casing in position to b 0%served through the aperture, said indicator tape having a series of lateral lugs, a slidable lead carrying element disposed 1n the casing and a pusher arm carried by the slidable element and adapted for engagement with said lugs to move the indicator tape in one direction when the lead carrying element is moved inward in the pencil casing.

2. In a device of the character described,

a tubular casing having a lateral aperture,

' cooperative pulleys disposed within the easing for movably supporting two juxtaposed endless indicator tapes, a gear integral with one of said pulleys, one of said tapes having a series of lateral lugs and a relatively long lug, the latter being adapted to engage wit the teeth of said gear to transmit motion intermittently from the first indicator tape to the second indicator tape, a slidable spring 10 lead to engage the firstindicator tape and 1 to transmit motion to'the latter.
